What Is Ready Mix Concrete?

Ready mix concrete is prepared according to a set mix design in a plant instead of a job site. Manufacturers mix sand, gravel, cement, and water, then deliver the mixture to the site, depending on the project requirement. Ready mix concrete is delivered in two ways—transit-mix concrete and shrink-mix concrete. With transit-mix concrete, the mixing process takes place inside the truck transporting the concrete. The concrete is partially mixed while in transit, and the full mixing takes place once it reaches its destination.

Mixing concrete in this manner prevents it from hardening during transit. By contrast, shrink-mix is partially mixed at the plant before being transported. Like transit-mix concrete, shrink-mix concrete is only fully mixed once it reaches the worksite. However, this type of mixing allows more concrete to be transported at once.

The character of concrete is determined by the quality of the paste. The strength of the paste, in turn, depends on the ratio of water to cement. The water-cement ratio is the weight of the mixing water divided by the weight of the cement. High-quality concrete is produced by lowering the water-cement ratio as much as possible without sacrificing the workability of fresh concrete. Generally, using less water produces a higher quality concrete provided the concrete is properly placed, consolidated and cured.

What Are the Benefits of Ready Mix Concrete?

Ready mix concrete is far better than other building materials in many ways. However, there are three overarching benefits that cover most of the perks:


Ready mix concrete is resistant to damage from any source, including high winds, fire, or even explosions. Additionally, it cannot be harmed by termites and other small creatures, thus eliminating the need for special treatments or sealants.

Concrete can also withstand heavy moisture and does not decay or warp like other building materials. Concrete can withstand extremely high temperatures, making it impervious to all Texas weather conditions. 


Ready mix concrete is highly flexible and can be molded into practically any shape. Whether you want to make a pillar, sculpture, or even just a driveway, ready mix concrete is the perfect material for your project.

Many people use chemical admixtures to change the color, porosity, and curing time of the concrete, further expanding their options for customizing their projects.


When compared to other materials that are used for construction like brick, ready mix concrete is far less costly. It is easy to apply and provides a uniform appearance when applied to any surface.

Brick, on the other hand, is difficult to even out and takes a lot of time, money, and resources to transport.

Things to Consider


You should always inform your supplier what you intend to make or repair with ready mix concrete. If we know what your project entails, we can provide you a mix that achieves the best result. Some applications require you to set the mixture slowly, whereas others require a faster setting of the mixture.

Depending on your project, we can make the necessary changes to the mix to get you exactly what you need.


Before ordering the concrete mixture, you should have a clear understanding of how much you need for your project. Ordering too much will result in wastage and additional cost, while ordering too little will result in delays until you replenish the stock. You should order at least 10% more than what is required so that you can cover up possible errors.

If you have any doubt about the quantity that you require, you can ask us, your ready mix concrete provider. We can help you determine the exact amount of concrete required for the project.

Ingredients Source

Ready mix concrete consists of different ingredients. The quality of each of the components determines the quality of the final ready mix. We only source the highest quality ingredients from reputable suppliers in your local area.


Once mixed, the ready mixed concrete should be used within a certain period of time. If it is not, you risk losing an entire batch. The movement of heavy concrete trucks during peak hours is restricted on major roads. This is done to prevent traffic problems. We will deliver to your project during non-peak hours to meet your timeline needs.
